Those interested can check out the ongoing thread for all of the related links including the FIFA12.MULTi10.PSN-EXEtrimALL and FIFA.12.PSN.PS3-iND releases, and below are some notes from pr0p0sitionJOE as follows:

Download ALL THREE PARTS (PKG) and install in order. People, game is almost 7 GB. Multiple languages inside. This is Full PSN version in one pack... not a fix.

For PS3 3.41 CFW users from Hissatsu:

FIFA Soccer 12 works on FW 3.41 without any special/extra FIXes. Tested myself its set to FW 3.40.

EXEtrimALL was kind enough to set the game to FW 3.40. So get your Soccer on!
